How does g(t) = 7^t change over the interval from t = 5 to t = 6? Choices: (A)g(t) decreases by 7% (B)g(t) increases by 7 (C)g(t) increases by 7% (D)g(t) increases by a factor of 7

Calculate g(5): Calculate g(5) by plugging in t = 5 into the function. g(5) = 7^5Calculate g(6): Calculate g(6) by plugging in t = 6 into the function. g(6) = 7^6Find factor of increase: Find the factor of increase from g(5) to g(6). Factor of increase = g(6) / g(5) = 7^6 / 7^5Simplify factor of increase: Simplify the factor of increase. Factor of increase = 7^(6-5) = 7^1 = 7Determine correct choice: Determine the correct choice based on the factor of increase. Since g(t) increases by a factor of 7, the correct choice is (D) g(t) increases by a factor of 7.
